Topic: Risk, prevention and care in population studies

Three survey rounds included 49 to 54 participants that agreed on VasCog-2 diagnostic criteria for preclinical, mild, and major dementia levels of vascular cognitive impairment (under the overarching term VCID). Research guidelines, including the use of novel neuroimaging and fluid biomarkers, were also agreed on. The World Stroke Organization (WSO) endorsed the criteria, hence named VasCog-2-WSO. Conclusions and Relevance: The VasCog-2-WSO criteria update the VasCog criteria for the diagnosis of VCID, providing operationalization and additional guidance on potential neuroimaging and fluid biomarkers. VasCog-2-WSO should provide an international standard for VCID diagnosis, facilitating diagnostic consistency among clinicians and researchers.

Key findings

Three survey rounds included 49 to 54 participants that agreed on VasCog-2 diagnostic criteria for preclinical, mild, and major dementia levels of vascular cognitive impairment (under the overarching term VCID).
Research guidelines, including the use of novel neuroimaging and fluid biomarkers, were also agreed on.
The World Stroke Organization (WSO) endorsed the criteria, hence named VasCog-2-WSO.
Conclusions and Relevance: The VasCog-2-WSO criteria update the VasCog criteria for the diagnosis of VCID, providing operationalization and additional guidance on potential neuroimaging and fluid biomarkers.
VasCog-2-WSO should provide an international standard for VCID diagnosis, facilitating diagnostic consistency among clinicians and researchers.

Why it matters

This paper presents updated international diagnostic criteria for vascular cognitive impairment and dementia, agreed on by experts and endorsed by the World Stroke Organization. It is about improving diagnosis and consistency, not about treating, curing, or preventing Alzheimer's disease.

How this study scored 61/100

Published in a leading specialty journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 59 of the 96 points we could judge it on, which is 61 out of 100.
